Re: warning speed camera

You just don't get it do you? You think speed relative to the speed limit is a measure of danger.

It isn't. Speed relative to something you might hit ahead is a measure of danger. 29mph with a 1,000 ton concrete block 2ft ahead would be extremely dangerous. 90mph on an empty motorway in good conditions would be very safe.

Anyway, faster roads are safer - it's not the speed in mph that brings the danger. It's the risk of collision in the first place.

If you travel fast where there's a risk of collision, that's dangerous. But never make the mistake of thinking that collisions materialise out of thin air and at random. They don't. Usually there's a series of mistakes by multiple drivers before there's a collision.

Tell me, what percentage of accidents do you think are caused by speeding?

: You just don't get it do you?

If motorists interact dangerously with pedestrians, of course many pedestrians will be lucky - primarily because the burden of caution is thrust onto them, rather than with the driver where it belongs. The point is that some will not, and where they do not, the results are catastrophic. Your paragraph above implies that near-misses are acceptable. They are not acceptable, IMHO, because they will not always result in a miss. Aircraft near-misses are viewed with extreme seriousness for the same reason.

: You think speed relative to the speed : limit is a measure of danger.

You are setting up a straw man. I have not said that, and you know it.

Let me make this as clearly as I can:

Speed relative to the risk is obviously the important criterion. I have not disputed that. This is why it is frequently safer to travel slower than the speed limit. I do not take issue with that, I take issue with your dismissive attitude to speed limits.

I contend that on a given road, a professional person has made a judgement about the speed limit that should be based on knowledge of the roads, risk factors, pedestrian and cyclist behaviour. The ordinary driver is not equipped to make the same judgement as they do not have access to the same data. [There may well be serious failings in that system that lead to limits that are arguably too low, but those failings must be addressed via the speed limit decision-making process, not in the field by non-compliance, or the result is an extremely dangerous form of lawlesness.] Given their general ignorance of the wider picture, then, drivers have speed limits imposed on them. As there is no objective means for dinstinguishing between between the drivers who know the road well and drive safely, and those that do not, there is no legal distinction that can be made between drivers either. Hence, the speed limits must be applied to all, without prejudice, or not at all.

The question then has to be whether we impose those limits or not. I maintain that, as there is a safety issue involved that impacts upon life and limb, they should be imposed, just as health and safety at work legislation is imposed. A driver who knows the road well may be able to drive within their limits at 40mph in a 30mph zone, where a driver who is new to that stretch of road may not. As I said, we must apply the limits without prejudice, so if either driver travels above the limit, an offence is committed, and punishment applied accordingly.

You appear to be arguing that it is necessary, even desirable, to travel above the speed limit. You are also arguing that you can correctly judge when your speed above the limit is safe. My contention is that, even if this latter point holds true in some cases - maybe even yours - there is a sizeable minority, possibly the majority, of drivers who do not have this ability, and certainly do not have the ability on roads that they are not familiar with. So, the speed limits are enforced to protect the all of the public from that proportion of drivers.

That is the point. It doesn't matter how good I am as a driver, or how good you are. There are people on the roads who have poor judgement. If they do so at an excessive speed, they multiply the risk to others, and the rest of us have a right to be protected from them, or at least to minimise the risk from them. The only objective measure we have of excessive speed is the speed limit. If you are a good driver, then there is no reason for you to be unable to keep within the limit.

: Anyway, faster roads are safer - it's not the speed in mph that brings : the danger. It's the risk of collision in the first place.

Again, you are comparing chalk and cheese, and appear to be looking at this only from the driver's perspective. Faster roads are safer because they are structured in a very different way, with barriers to prevent head-on collisions and interactions with pedestrians or cyclists (motorways and dual carriageways), or pass through areas with lower risk of interactions with pedestrians. Slower roads, almost by definition, exist where there is a high density of non-drivers.

'Faster roads are safer' - Are you seriously arguing the case that it is the speed that makes it safe, and no other factors are involved? If the 30mph speed limit through a small town is upped to 70mph, would the casualty rate decrease? If not, does this not indicate that maybe there are good reasons for speed limits?

: If you travel fast where there's a risk of collision, that's : dangerous. But never make the mistake of thinking that collisions : materialise out of thin air and at random. They don't. Usually there's : a series of mistakes by multiple drivers before there's a collision.

Another straw man. No-one's disputing that. The fact is that when those events occur, higher speeds dramatically reduce the available response time for the avoidance of collisions, and result in greater damage when those collisions do occur.

: Tell me, what percentage of accidents do you think are caused by : speeding?

What I *think* is irrelevant. The DoT, the AA, and parliamentary review committees put the figure at over 1000 deaths per annum resulting from accidents where excessive speed was the primary causal factor - not the only factor, but the primary one. If only a tenth of those deaths involve speeds that could have been avoided by keeping within the speed limit, then that's 100 deaths too many. You may think that's an acceptable price to pay for you to reach your meeting on time or to retain your libertarian ideals, but I'm afraid that I do not.

Well, EXACTLY. It is not speed that makes the near misses into tragedies. If we concentrate on complete avoidance of incidents we'll do much better. Industrial health and safety takes this approach because it works. They don't say: "max ladder height 10ft" because it'll hurt more if you fall off from a higher ladder. They tell you how not to fall off a ladder.

I don't dismiss speed limits. I dismiss automated enforcement.

False. If drivers didn't make very reasonable choices of speed they would crash a hundred times more frequently. If you are going too fast to stop when you approach a hazard you crash. Simple as that. Drivers stop in good times countless millions of times each day. Therefore they were not going too fast. The average driver goes 7 years between accidents. If the average driver was constantly going too fast they would be lucky to last 7 weeks.

We're not allowed to consider circumstances? Why ever not? We always used to.

This characterisation of safe / unsafe based on local knowledge is just rubbish. The safe speed is dictated by instantaneous conditions.

And so they should be. It isn't hard for a skilled traffic officer to recognise a vehicle travelling at an unsafe speed. They don't need to measure the speed in mph to know - but I'd be happy if they then measured the speed in mph to prosecute.

Yes there is. It would be a massive waste of resources. Drivers everywhere exceed the limits when and where it is safe to do so. The average speed of cars on motorways is in excess of the speed limit.

False. Faster roads are only faster because drivers choose to travel faster on them. They know it is safe to travel faster and they do travel faster. Do you really think if we abolished all speed limits that village high streets would be driven at the same speed as motorways? Sheesh!

There are excellent reasons for speed limits.

But it's important that we consider the possibility of creating accidents with a poor safety strategy. Speed camera philosophy completely misses that vital point. They have never investigated the risks which may be caused by "excessive" speed enforcement.

I seriously believe that speed cameras kill people. So your final argument is wasted on me.

The 60mph and 70mph NSLs were set many many years ago (1960s?), when brakes and tyres were nowhere near as good as they are now.

It would be great if siting of speed traps were done by such a process, but it's all to often done on roads where higher speeds are safer, and done in order to raise revenue.

If the means of enforcement distracts drivers it may be less safe.

If the messages given to drivers to support the scheme of enforcement are false it may be less safe. (e.g. some drivers end up believing that they are safe purely because they are not exceeding a speed limit)

I keep a 17 point list of actual and potential dangers from speed enforcement.

Intelligent enforcement is just fine. Excessive robot enforcement messes up drivers priorities and so reduces their ability to avoid accidents.

Because sound government depends on the consent of the governed. Government intervention in people's lives is only justified when that intervention serves some purpose.

If the purpose served is safety, then people will tend to consent to it and support it. If the purpose served is drumming up a bit of revenue, then the public consent won't be there, and the legitimacy of the interventionn is diminished.

NB the *legality* would still be there if the Gov't openly advertised that it was going to trigger cameras at 31mph for revenue purposes. But the *legitimacy* wouldn't be there.

(FWIW, I reckon people would be a lot less bothered about revenue cameras if it wasn't for the three points on the licence.)

Why should it distract drivers? Why should it distract drivers any more than the alternatives that you offer based upon a police presence on targeted black spots etc?

So it is not the use of speed cameras that are the problem, as much as the advertising campaigns, literature and training that accompany them? These I suggest are separate (if related) issues.

I am aware of your list. Some of the points hold some merit, although I think some are tenuous and fanciful.

Surely this is not the fault of the law enforcement so much as the drivers understanding of and attitude towards it.

I see loads of little shunts on my road it's a 30 mph limit I probably see 1 accident a week on my travels on the motorways but what do you consider a collision wing mirrors being ripped of is a collision but so is doing 70 mph into the back of a stationary lorry who's just stopped because of the traffic ahead figures can be manipulated to do any number of things but there needs to be a total rethink of the limits that are in place on the roads now just because you are going slower doesn't drastically reduce the risk of an accident it just means that the damage isn't as great and you have more people looking at you when they crawl past in order not to get tugged by plod for breaking the speed limit :)

Because it gives them something else to worry about. Even if they intend to continuously comply the treat of prosecution is a distraction from the basic task of driving safely. It doesn't have to be a big distraction to create potential danger - even (say) 0.5% of a driver's concentration absorbed in this way will create some danger.

Because the emphasis changes from "obey the limit" to "always drive safely" - we get the priorities right.

The current dangers are system wide and include such factors as reduced traffic police and over simplistic messages given to drivers. It's quite possible that the messages are a specific dangerous component, but the loudest message is: "we'll nick you if you break the speed limit". It seems to me that the cameras themselves say that unaided.

It's intended to be a comprehensive list. I don't think any of the items are "fanciful" but a few of them may be insignificant. The important point is that we won't really know until someone does the research.

It is the fault of the enforcement. Sticking rigidly to the speed limit is a low safety priority. If we make it a high enforcement priority we automatically distort drivers' safety priorities. That's dangerous.
